SPARK-ARR ESTER.

SPECIFICATIN forming part of Letters Patent No. 331,072, dated November 24, 1885.

Application tiled September 8, 1885. Serial No. 176,472. (No modcl the city of Indianapolis, county of Marion,

and State of Indiana, have invented certain .new and useful Improvements in Spark-Ar resters, of which the following is a specification.

My present invention consists in various improvements on that construction of spark-arresters shown in Lettersl Patent No. 314,254, granted to me on March 24, 1885, by the use of which said spark-arrester is rendered more perfect in operation, more convenient to clean, and less liable to become clogged by sweat7 or cinders, as will be hereinafter more particularly described.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure l is a side view of a locomotive provided with my said invention, one side of the smoke-box being broken away to show its location and arrangement; Fig. 2, a front elevationllof said invention and surrounding parts as seen when looking to the left from the dotted line 2 2 in Fig. l; Fig. 3, a central vertical section through the device separated on the dotted line 3 3 in Figs. 4 and 5; Fig. 4, a crossseetion looking downwardly from the dotted line 4 4 in Fig. 3, and Fig. 5 a similar view on the dotted line 5 5 in same figure.

In said drawings, the portions marked A represent the boiler; B, the smoke-stack; G, C2, C3, O4, C5, and C, the several parts of the spark-arrester proper, and D areceptacle for the sparks.

The boiler, smokestack, and surrounding parts are or may be of any ordinary or suitable construction, and therefore need no special description. The screen and inverted cone commonly used in the smoke-stack are, however, omitted, leaving said smoke-stack entirely free from obstruction.

As in the aforementioned Letters Patent,the body of the spark-arresting device is composed of several parts, which are arranged in substantially the same general manner. The upper part, C', is perforated and connected to the lower end of the smoke-stack. The second part, G2, is connected to the rst and extends down a short distance, surrounding the inner portions. Itis provided with a funnelshaped top, c, inclined from its front to rear side. Around the edge of the central opening therein, and cast integrally with said top, is an upwardly-projecting pipe, c', which extends up about to the lower edge of the perforated part C', and thus conducts the exhaust and smoke from below directly into the upper draftand prevents it from expanding into the enlarged portion just below the part C and impairing the draft. ily seen,this pipe can be made adjustable, if desired, by simply adding a section of pipe, as shown in dotted lines, which can be adj usted up or down, as the weak or strong current of the exhaust from below seems to demand. Said part is also provided with an inclined bottom, c?, terminating at its lowest point in an orifice, c3, connected with a spout, d,which leads to the spark-receptacle. rlvlhe third portion, C3, is secured in the opening in the bottom ofthe part C?, and extends up within said part about two-thirds of the way to the top thereof and down a short distance below said bottom, as shown. The fourth part, G4, is se` cured to the lower end of said part Gand extends down nearly to the bottom of the device. It is preferably formed flaring from its top to its bottom, and is secured to said part C3 by bolts or catches, so as to be easily detached when it is desired to get to the inside of the apparatus for any reason. A perforated pipe, C5, is mounted within said parts C3 and C4, its top being connected to the lower edge of the top c of the part C2, and its bottom having a base-plate, c4, secured there- As will be read on, which sets onto the exhaust-nozzle a, said l plate being provided with an opening which registers with said nozzle, around which is preferably formed a flange, c5, somewhat contracted toward its end to form a perfect nose to said nozzle, as shown. In the lower front side of said pipe I provide a door, c6, and thus when it is desired to get to the inside of said pipe to clean it out, or for any other reason, it can be readily done by simply detaching the part C4 and opening this door, thus giving ready access to the nozzle and interior of the apparatus.

rIhe pipe G6 is mounted around and is adapted to move upon the pipe C5, it also being perforated, said perforations being in the IOO shape of elongated slots in each of said pipes. It is ofsubstantially the same length as the pipe C5, its lower end resting upon a projecting edge of the base-plate c4, except at its front side, which is preferably cut away from the top of the door c to permit the free operation of said door. (Of course this part could also be provided with a door covering the door -in the part G5, if preferred; but I do not deem `catch-piece on the side of the cab. Thus when from sweat or any other cause theperforations in said pipes become clogged, or cinders become lodged therein, and the operation of the apparatus thus becomes impaired, the engineer or fireman, by simply taking hold of the handle von the end of said rod A2 and giving itashake, operates, through the connecting-arms and the shaft A, to move the pipe C6 back and forth upon the pipe C5, and cut off all adhering cinders, soot, or other clogs, and frees the perforations from all obstructions, and permits the free and unobstructed operation of the mechanism. By

this means the operator is also enabled to partially or entirely close said perforations when from any cause it is desired so to do, the notches in the handle being arranged so as to bring said two pipes in exactly the various relative positions that may be desired.

The receptacle D for the sparks is usually located in front of the smoke-box on or in the frame-work of the cow-catcher. Its front top portion is formed of a separate piece, d', bolted in position, and thus if anything should be caught by the cow-catcher and thrown against said part, breaking it, it could be readily replaced without disturbing the receptacle proper. Its lower portion is preferably hopper-shaped, and is provided with a discharge-door, d?. Said door is formed in the shape of a half-ball, its curve side fitting into the opening, and thus insuring a tight joint at all times, as all cinders andother matter which would become lodged upon a fiat door and prevent it from being closed tightly will slide off from this by reason of its formation. It is hinged at one side, and at its other side is preferably connected back to an operating-lever, D, in the cab by means of the rod d3, levers di, operating on the rock-shaft d5, and the connecting-rod d, thus permitting the operator to empty said receptacle from the eab at any time, and then tightly close it again.

lIn general operation my improved apparatus is not dissimilar from that shown in the aforementioned Letters Patent, the exhaust entering through the nozzle a, and the smoke being drawn in through the perforated ypipes into the smoke-stack, while the cinders are carried up over the top of the part G3 into the part G2, and thence to the receptacle D, as therein but by the use of these improvements I provide means for keeping the perforated pipes free from obstruction, means for regulating the draft, and access to the interior of the device, as has been fully set forth.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, isn

l. The combination, with a spark-arrester secured in the smoke-box, of an internal double perforated pipe, one part of which is adapted to move upon the other, whereby said perforations may be kept unobstructed, substantially as set forth.

2.
